Subject: November 2021 Semi -Annual Sampling Report
Cabarrus County C&D Landfill
Facility Permit No. 1302-CDLF-2006
Dear Ms. Drummond:
CDM Smith Inc., on behalf of Cabarrus County, is submitting an electronic copy of the November 2021
semi-annual sampling event report for the Cabarrus County C&D Landfill. This letter report presents the
results of the recently completed sampling at the C&D Landfill and constitutes the second semi-annual
sampling event for 2021.
The approved monitoring well network for the C&D Landfill consists of background wells CD -Is and -1d;
compliance wells CD-2, -4 Rep, -7, and -9; and surface water sample location SW-3. CD-4 Rep was
installed in January 2009 as part of the proposed Phase 1 C&D Landfill expansion. Monitoring well CD-7,
formerly piezometer B-7, was added to the monitoring program in July 2014 as part of the Phase 2 C&D
Landfill expansion. Monitoring well CD-9 was installed on March 19, 2017, as part of the Phase 3 C&D
Landfill expansion. Field activities and sampling results for the groundwater and surface water samples
are discussed below.
Field Activities
Groundwater samples from the Cabarrus County C&D Landfill were collected on November 16-17, 2021.
Surface water sample location SW-3 was dry during the November 2021 sampling event. Groundwater
samples were collected from the monitoring wells by use of disposable, laboratory decontaminated
bailers. Monitoring well locations and the surface water location for the C&D Landfill are provided on
Figure 1.
Groundwater elevations were measured at each well on November 15, 2021, prior to sampling and are
presented in Table 1. Well construction details for each monitoring well are also provided in Table 1.
These groundwater elevations were used to construct potentiometric contours for this sampling event
and are presented on Figure 1. After depth to groundwater was measured, each well was purged prior

to sampling to provide fresh formation water within the well water column. Each purge volume was
measured for pH, conductivity, turbidity, temperature, dissolved oxygen, and oxidation-reduction
potential using a YSI-556 multi -parameter water quality meter and a HANNA HI 98703 turbidity meter.
The water quality parameters at the time of sampling are presented in Table 2.
Sampling Results
Pace Analytical Services, LLC, located in West Columbia, South Carolina, analyzed the groundwater
samples for North Carolina Appendix I volatile organic compounds (VOCs) plus tetra hydrofuran, North
Carolina Appendix I metals plus iron, mercury, and manganese, alkalinity, total dissolved solids (TDS),
chloride, and sulfate except for CD-4 Rep. Samples collected from CD-4 Rep were analyzed for North
Carolina Appendix I VOCs and metals.
In a letter dated May 28, 2019, the Solid Waste Section requested that all groundwater and surface
water samples collected from landfills be analyzed for 1,4-dioxane after July 1, 2018. On July 1, 2019,
the Solid Waste Section approved the removal of 1,4-dioxane from the sampling program due to two
consecutive non -detect events (January and May 2019), except for SW-3.
The analytical results were reported to the laboratory specific method detection limit (MDL) and are
quantifiable at or below the method reporting limit (MRL). All monitoring wells for the C&D Landfill had
detections of analytes above the MDL but below the MRL. These detections were qualified as estimated
or "J" flags. In samples collected from CD-4 Rep, a detection of copper had a "B" flag, indicating that the
analyte was detected in the method blank.
The following list indicates the analytes detected above the MRL at each sampling location. No "J" flag
detections are provided. Underlined analytes exceeded the 15A NCAC 02L .0202 (NC 2L) Groundwater
Standard or Interim Maximum Allowable Concentration Standard.

"J" flags were not included in the previous list, but several locations had "J" flag detections that
exceeded the standards. These constituents along with their location are listed below.
Antimony: CD-1d
Vanadium: CD-1s and -9
Equipment and trip blanks were analyzed for quality control. A duplicate sample was also analyzed for
quality control. Chromium was detected as an estimated concentration and copper was detected in the
equipment blank below their respective NC 2L Groundwater Standards. There were no detections in the
trip blank above the MDLs. The duplicate sample, identified as C&D-DUP, was collected from CD-7. The
duplicate sample had similar concentrations as those detected in CD-7, except for a detection of lead in
the duplicate sample and an estimated detection of tetrachloroethene in the parent sample below their
respective NC 2L Groundwater Standards.

Metals detected above the standards are likely naturally occurring based on concentrations in the
background monitoring wells or are from elevated turbidity at the time of sample collection. Benzene,
1,1-dichloroethane, and vinyl chloride were detected above their respective NC 2L Groundwater
Standards in samples collected from CD-2 during the November 2021 sampling event.
1,1-Dichloroethane is the only VOC that has previously been detected above the standards in CD-2, in
September 2020. 1,2-Dichloroethane was detected above the NC 2L Groundwater Standard in samples
collected from CD-4 Rep during the November 2021 sampling event. This is the first VOC detection in
CD-4 Rep above the standards. Benzene, tetrachloroethene, and vinyl chloride were detected above the
NC 2L Groundwater Standards in samples collected from CD-7 in 2019 and during the November 2021
sampling event. In September 2020 and March 2021, only vinyl chloride was detected above the NC 2L
Groundwater Standard.
A complete summary of all detected constituents from the November 2021 sampling event is presented
in Table 3. The laboratory analytical reports are provided in Appendix A. The next semi-annual sampling
event will be completed in the spring of 2022.
If you have any questions or require further explanation, do not hesitate to call me at [phone] or

Very truly yours,

Notes:
1. All units are in micrograms per liter (parts per billion).
2. "- Interim Maximum Allowable Concentration (IMAC)
3. NE -Standard Not Established; dup - Duplicate Sample; (--) - Not Analyzed
4. CD-4 Rep was installed as part of the proposed Phase 1 C&D Landfill expansion in January 2009. Beginning November 2011 samples collected from CD-4 Rep are only analyzed for Appendix I metals.
5. CD-3 was relocated on July 1, 2014, as part of the Phase 2 C&D Landfill expansion. CD-7 and -8 (formerly piezometers B-7 and -19) were added to the monitoring program in July 2014 as part of the Phase 2 C&D Landfill expansion. CD-3 and -8 were
abandoned on February 2, 2017, as part of the Phase 3 C&D Landfill Expansion.
6. CD-9 was installed on March 9, 2017, as part of the Phase 3 C&D Landfill Expansion.
7. J - Indicates the analytical result is an estimated concentration between the method detection limit and the adjusted reporting limit.
8. B, B-01- The analyte concentration detected in the method blank was greater than the method detection limit.
9. CN - Detected silver concentrations were determined to be the result of contamination from the preservative acid used.
10. H-02, H1- Analysis was completed outside of hold time.
11. S -The laboratory had a matrix spike/matrix spike detection failure.
12. Alkalinity, chloride, sulfate, and total dissolved solids were added to the sampling program in May 2010.
13. (1) - Not analyzed due to laboratory oversight.
Concentration exceeds the 15A NCAC 02L.0202 (North Carolina 2L) or IMAC Standard
- Indicates the result is below the detection limit.

3. CD-4 Rep was installed as part of the proposed Phase 1 C&D Landfill expansion in January 2009.
4. CD-3 was relocated on July 1, 2014, as part of the Phase 2 C&D Landfill expansion. CD-7 and -8 (formerly piezometers B-7 and -19) were added to the monitoring program in
July 2014 as part of the Phase 2 C&D Landfill expansion. CD-3 and -8 were abandoned on February 2, 2017, as part of the Phase 3 C&D Landfill Expansion.
5. CD-9 was installed on March 9, 2017, as part of the Phase 3 C&D Landfill Expansion.
6. J - Indicates the analytical result is an estimated concentration between the method detection limit and the adjusted reporting limit.
7. B - The analyte concentration detected in the method blank was greater than the method detection limit.
8. NE - Standard Not Established
Concentration exceeds the 15A NCAC 02L .0202 (North Carolina 2L) Standard.
